FRANK IVI. STOLL, OF DENVER, COLORADO.

PORTABLE .AND COLLAPSIBLE BED.

Application filed March 21, 1922.

To all 107mm t may concern.'

lle it known that l. FRANK M. SToLL, a citizen of the United States of America.. residiiw' at Denver, in the cour v of llenver and state of Colorado. have invented certain new and useful. Improvements iu Portable and (lollapsible Beds, of which the following` is a specification.

The invention relates to portable and col- ]0 lap l'ble beds, more particularly of the type used by *ampers and autoists and has for its principal object the provision of abcd of this character which can be quickly and easily set up or collapsed and in which thex spring structure can be stretched 'taut with a minimum. of effort.

Another object of the invention is to reduce the number of parts usually .found in beds of this character so as to lighten the bed and reduce the cost of manufacture.

Further objects of the invention reside iu. the detail construction thereof and in the ways and means of connecting the various detachable parts. These objects will become apparent from the following' description.

rlhe invention will now be described with reference to the accompanying drawing which forms a part hereof. Corresponding and like parts are referred to in the description and indicated in all views of the accompanying drawing by the saine reference characters.

ln the drawing:

cross members in the folded or position.

Let the numeral 10 designate a springI structure of the usual construction, haviim` a series of longitudinal. flexible members "1l, terminating in springs 12. Spring structure 10 is suspended between two end bars 11E and 14, shaped in cross section.

The supporting frame of the bed consists of two jointed longitudinal members 15, pivoted at each of their extremities to leg members 16. Pivot-ed to each of the longitudinal members as shown at 17 is a cross brace 18. which is detacliably connected to the opposite longitudinal member as shown in F 4. rlhe end of cross brace 15S is bifurcated. The two sides of the bifurcation are turned in opposite directions at right angles forming a T shaped head 19 on the free ends of the cross braces 18 as shown at 19. A socket 2O is formed on the opposite longitudinal member and is adapted to receive this T shaped head 19 which is se curely locked therein by means of a pivoted button 21, which may be turned to prevent its removal.

Cross brace 18 serves to brace the bed against side sway and also to hold the supporting frame upright while the springstructure 10 is being put in place.

Leg members 16 are L shaped in cross section. At their upper extremities one leg of the L is allowed to project beyond the other and is turned to form a hook E22.` These projecting hooks 22 are adapted to pass through openings 23, formed in end members 13 and 11, and hook over the edges thereof. Diagonal braces 24 are pivoted to end members 13 and 14 opposite openings 23 in such manner as to cause their upper extremities to engage the leg members 16, when said diagonal braces are turned at right angles to the end members 13 and 1-1, as is clearly indicated in Fig. 3, thus preventing the hooks 22 from becoming disengaged while the bed is extended.

This simple method of locking the end members 16 to the leg members 13 and 14, without the use of screws7 clamps, wedges, etc., is believed to be new and novel and is one of the features of the invention.

The lower extremities of the diagonal braces 24 are provided with projections 25., which engage in openings in the upper faces of the longitudinal members 15.

collapsed llO Longitudinal members 15 are U shaped in cross section7 the open face of the U pointing downward, and are each formed of two sections pivoted together. The nner extremity of one section carries pivot pin 26 which engages in a slotted opening 27 formed on the inner extremity of the connecting section. The section carrying the slotted opening fits Within its connect-ing section so that the two can be telescoped Wit-hin the limits of the slotted opening 27.

Mounted on one of the sections, and pivoted thereto, is a lever arm Q8, provided with a hand hold 29 at its longer extremity and with a pivoted link 30 at its shorter extremity. The link 30 is provided with a notch 31 at its free end. which is adapted to engage a` stud 32, fixed in the opposite section of the longitudinal member 15 to that carryii'ig the lever arm 2S. An opening 33 is formed in the top of each of the longitudinal members 15 an( aiflapted to be engaged by the extremity of the handle 29.

When collapsed, ready for transporting, the two longitudinal members 15 are folded, as indicated in Fig. 8, with the leg members 16 folded Within and the cross brace 18 folded thereon. Lever arm 28 with link 30 folded back thereon lies parallel with the longitudinal members 15, the free end thereof engaging the opening The spring structure 10, with the diagonal braces Et folded within the L shaped end members liet and 18, is Wrapped around the two folded longitudinal members 15, the Whole forming a compact bundle.

The bed is erected as follows. The two sections of the longitudinal members 15 are slid upon one another until the pivot pin 26 occupies the outer end of the slot 2i'. The sections can then be revolved about the pivot pin 26 to their extended position, when the sections are again slid so that the pivot pin Q6 occupies the opposite end of the slot 27, thus foreshortening the longitudinal menibers 15. The leg members 16 are turned at right angles to the longitudinal members 15 and the cross braces 1S connected. The frame is now self supporting. End bars 13 and 14: are now slipped over the projecting hooks 22 of the. leg members 16, and the diagonal braces 24 brought into position and placed in openings in the longitudinal menr bers 15. rl`his placing of the diagonal braces simultaneously locks the end members 13 and 14 to the leg members 16.

The placing of end bars 13 and 1a and the diagonal braces Qa is facilitated by the fact the longitudinal members 15 are foreshortened and the spring structure 10 is in a. slaclrened or loose condition.

The longitudinal members 15 are now in the position as shown in Fig. 5. Levers 28 are now opened to the position shown (Fig. and the linls 30 connected to the studs 3Q. The levers 28 are then forced bara to their original positions7 thereby lengthening the longitudinal members from the broken. line positions shown in i.figs. ('3 and 'i' to the solid line positions in the same riens. rllhis lengtheningT of the longitudinal inembers 15 stretches the spring structure taut. and ready for use. Link 30 is pro-vided with a raised portion Se in orderl to allouT the link to pass over the pivot pin in 'the lever 28.

Having thus described my invention7 what claim and desire to secure by Letters Patent is:

1. A collapsible bed comprising end mem bers; a flexible spring structure connecting said end members; leg members provided With hook shaped upper extremities, said extremities adapted to pass tlnfough openings in said end members; dia; nal braces pivoted to said end members ami adapted when extended to engage said extremities and lock same in place and longitudinal members pivoted to and separating said leg members.

2. A collapsible bed comp ising end members supporting aflexible spring structure; leg members adapted to detachablyv said end members; extendable lon members pivoted to and separating said leg members; diagonal braces piroted to said end members and detachably engaging said longitudinal members; cross braces plvoted to each of said longitudinal members and detachably engaging the opposite longitudinal member and means for extending said longitudinal member for the purpose of tightening said spring structure.
